A fun little game and pleasing to play, however the main flaw comes with how much the upgrades cost / how slowly you gain the gems. It could also do with a refund system. My main gripe I have with the game is Rarity, the game makes her out to be a good source of gems and so I bought her first, however the amount of gems she obtains combined with her low fighting ability makes her just a gem sink rather than a gem farmer. If Rarity is changed to make more gems, the gems overall made more abundant (not halving the amount after a victory) and the prices are reduced to make there no need to farm then this game would be a sure fit hit. However as it stands I sadly don't feel like playing past Discord (where I first had to begin farming due to the previous Rarity gem sink)
